Reactive power control with voltage limiting function Q(Ulim)
In ByVoltageLim
operation mode, the voltage-dependent limiting characteristic curve Q(Ulim) is active for reactive power control. Configuration is carried out via the ReactiveByVoltageLim
parameter group (see ReactiveByVoltageLim).
The characteristic curve is based on a fixed lookup table with four operating points and is implemented in accordance with the specifications of the VDE standards. The operating points are preset by default in accordance with VDE-AR-N 4110. A horizontal offset of the characteristic curve is possible via the ReactiveByVoltageLimOffset
parameter.
The resulting characteristic curve with the associated parameters is shown in the following figure.
